This invention relates to gelatin band spindles for hectographduplicating machines and its object is to provide a novel and improvedspindle adapted to be readily and easily mounted in a machine and to beengaged with carrier devices for storing the roll.

A further and important object of the invention is to provide a strongand substantial spindle comprising a body made of wood or other lightmaterial and provided with metal journal end members permanently andrigidly secured to the body so that they will not twist or turnrelatively to the body 111 service.

And a further object of the invention is to provide an adapter forenabling the spindle to be used in a variety of machines.

In the accompanying drawings illustratin a selected embodiment of theinvention,

Fig. 1 shows the spindle mounted in parts of a machine shown in section.

Fig. 2 is a sectional view through the spin dle, the adapter and theparts of the machine in which they are mounted.

ig. 6 is a perspective view showing the left end of the body and themetal journal end member to be engaged therewith.

Referring to the drawings, 8 is the body of the spindle which may bemade of wood or other light material and of a suitable size. The body isprovided with metal journal end members 9, 9, which are preferably madealike. Each journal end member 9 has a socket portion 10 to receive anend of the body which is reduced to form a peripheral shoulder 11 toabut the socket wall, whereby the end member will lie flush with thebody and present a smooth surface to receive the gelatin band. The endmember is secured on the end of the body against relative rotativemovement by any or all of the following means :The side wall of the endmember may be indented at any place or places, as at 12, to clamp thebody; the bottom of the socket may be provided with a transverse rib131:0 engage a corresponding groove 13 in the end of the body; or one ormore sharpened ribs or projections of suitable size may be provided onthe inside of the socket wall to cut into the body 8 when the end memberand the body are engaged. The rib and groove are preferred because theywill. absolutely insure against relative rotative movement of the bodyand end member, but the sharpened ribs or projections 13 con stitute asatisfactory interlocking means for many purposes; and the indentations12 are a desirable feature since they can be easily made to press intothe Wood body and prevent relative rotative and also relativelongitudinal movement of the body and end member. There is oftenconsiderable rotative strain on the spindle and heretofore it has notbeen uncommon to find the body rotating relatively to the end members ofthe spindle, but there is little tendency of the body and end members toloosen or separate longitudinally, therefore it will be found suflicientordinarily to provide the rib and groove for preventing relativerotative movement and one or more indentations like, or similar to 12 toprevent relative endwise movement.

I prefer to make the end members alike so that they can be usedinterchangeably in the supporting parts of a machine or of a storagecarrier and I provide each end member with an elongated journal 14 whichprojects beyond the other parts of the end member and is adapted toengage supporting parts in the machine or the storage carrier.

In Figs. 1 and 2, the journal at the left of the spindle is shownengaged with an adapter 1:") including a screw-threaded stem 18 fast ina member 16 which is rotatably mounted in the machine frame (not shown)or the like. Unitary with the adapter 15 is a centrally located boss 21projecting axially from the adapter and an openin 22 extends through theboss and into the main body of the adapter and is enlarged as at 23 andthe outer end of the opening is countersunk as at 24.

Extending outw: 'dly from the boss 21 is a lug 25 and the sides of thislug extend radially from the boss. Projecting axially from the ends ofthe end members 9 at the periphery thereof and spaced from the elongatedjournals or center pins 14 are lugs 26. These lugs are spaced from eachother and when the center pin ll is passed through the opening 22. thelug 25 its between adjacent lugs 26 which are circuniferentially spacedfrom each other. I prefer to provide three lugs 26 for then when the lug25 is titted between adjacent hws and the adapter 15 is rotated ineither direction the hip; is so disposed relative to two lugs 26 thatthe spindle will start to turn at once. However, the end members 9 needhave but one lug for the adapter 15 may be rotated in either directionand the lug 25 sooner or later will engage the single lug 26 and causerotation of the spindle. Thus, while the provision of three lugs isadvantageous one or more lugs may be provided without departing from thepurview of my invention.

The invention provides a strong and substantial spindle for gelatinbands which is adapted to be readily and quickly engaged with anddisengaged from the parts of a duplicating machine for supporting thespindle, and also with a carrier in which the gelatin band roll isstored when not in use. I prefer to dispose the sides 27 of the lugsradiall of the spindle to make the spaces be tween the lugs as wide aspossible at the periphery of the spindle where they will be firstengaged with supporting parts. Furthermore, since the sides of the lugs26 are in radial planes the sides of the 111;;25 will neatly h'tthereagainst to provide a good driving connection between the lugs 25and 26. I have provided strong and substantial metal journal ends andnovel means for securing these ends on the body because I know that inpractice it not infrequently happens that the journal ends are broken ordistorted in use or in handling and work or are forced sufficiently freeto revolve on the body or to permit the body to revolve relativethereto. The journal ends of my invention are strong and substantial andare rigidly and permanently secured to the body.

I have shown the invention in a preferred form adapted for commercialuse, but I reserve the right to make changes in the construction andarrangement of parts within the scope of the following claims.
